                      REPORTS RESULTS OF MARCH 31, 2004 AND
              FILES AMENDMENT TO DECEMBER 31, 2003 QUARTERLY REPORT

BCSB Bankcorp,  Inc.  (NASDAQ:  BCSB),  the holding company for Baltimore County
Savings Bank, FSB,  recorded earnings of $161,000 or $.03 for the quarter ending
March 31, 2004.  This compared to $779,000 or $.14 per share for the same period
in 2003. The reduced earnings reflect reduced interest income during the quarter
as interest and fees on loans  decreased along with the average balance of loans
receivable.  Management attributed the decreases to increased competition in the
mortgage  refinance  market,   current  economic   conditions  and  management's
reluctance to make long term loans in the low interest  environment that existed
during the  quarter.  For the six months  ending  March 31,  2004,  total assets
equaled  $731 million as compared to $668  million on  September  30,  2003,  an
increase of $62.5 million.  Total deposits  continued to rise to $578 million as
of March 31, 2004 as compared to $552 million on September 30, 2003.

The Company will shortly be filing an amendment to its Quarterly  Report on Form
10-Q for the  quarter  ended  December  31,  2003 to  restate  its  consolidated
statement  of financial  condition as of December 31, 2003 and its  consolidated
statements of operations for the three months ended December 31, 2003 to correct
the  accounting  treatment  for a Bank Owned  Life  Insurance  ("BOLI")  policy.
Subsequent to the issuance of the Company's consolidated financial statements as
of and for the  three  months  ended  December  31,  2003 and the  filing of its
Quarterly  Report on Form 10-Q for the quarter  ended  December  31,  2003,  the
Company  determined  that  it had  incorrectly  accounted  for  its  income  tax
provision related to the BOLI policy. The effect of the restatement is to reduce
the  Company's  income tax  provision  to  $53,708  for the three  months  ended
December 31, 2003 from  $91,560  previously  reported,  thereby  increasing  net
income from $188,057, or $.03 basic and diluted earnings per share, to $225,909,
or $.04 basic and diluted  earnings  per share.  Total  stockholders'  equity at
December 31, 2003 increases to $44,309,111 from $44,271,259 previously reported.
